Altering the liblockfile configure script the following way eliminates the
problem after a make clean:

-- orig --
if test "$GCC" = "yes"; then
    CFLAGS="$CFLAGS -Wall -D_GNU_SOURCE"
fi

-- patched --
if test "$GCC" = "yes"; then
    CFLAGS="$CFLAGS -Wall"
fi

That seems to be a bug in your toolchain then, it builds with the standard
toolchain in BR (4.3.2) for me.

What's the reason for using a crosstool toolchain instead?

I use the current toolchain when compiling my kernel.  I was simply trying to
maintain the same toolchain across all builds, but it looks like that may not
be the best track to take.

It's a problem with new glibc which added the eaccess function in unistd.h
under the _GNU_SOURCE flag.
It's been fixed in later verions of liblockfile :
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=392779.

I just compiled a buildroot with liblockfile version 1.08. Please update the
version in buildroot.
